Product information
The ISPM25 series multi-functional power parameter measuring instrument provides cost-effective measurement solutions for public/commercial buildings, industries, energy and infrastructure, power grids and public utility customers. The ISPM25 series is standardly equipped with an RS485 communication interface and has various IO expansion functions that can be flexibly selected according to needs. It is widely used in power distribution cabinets, SCADA systems and energy efficiency management systems, substation automation, distribution network automation, community power monitoring, industrial automation, and intelligent buildings. With 0.2-level accuracy for current and voltage and 0.5-level accuracy for power, it can meet the application needs of high-precision monitoring, internal sub-metering, and energy efficiency management. The opening sizes of 85*85mm and 68*68mm make it very suitable for various installation methods. It is easy to install, with simple wiring and small engineering volume. It can be programmed and set on site, and can complete the networking of different PLCs and industrial control computer communication software.
